Memetics consists of terminology and framework for cultural evolution. Cultural evolution covers a lot of hypotheses. For instance there’s the hypothesis that the human brain swelled up to accommodate memes or the hypothesis that memes made humans sociable—since they need social contact between their hosts in order for them to reproduce—or they hypothesis that memes were implicated in the high frequency of speciation among our ancestors—just as songbirds speciate frequently. There’s quite a lot of associated hypotheses—no doubt some are correct and some are not.
